Re: [Quantlib-users] Question about changing ql.Settings.instance().evaluationDate in class Setting asynchronuously

[Josep R. <jos...@gm...>]

Hello,

If with asynchronously you mean with multiple threads I would say the
standard answer is no (or it used to be).

I think using some compiling flags and taking care of some things it would
be possible but is not meant to be used that way.

Check the answer from Luigi Ballabio. below as it might help.

Thank you,
